TILE-MACHINE.

Specification of Letters Patent.

Patented April 30, 1907'.

Annlication filed Tune 22,1906. Serial No. 322,933.

To all 1.0710110 H Hamil/0070067721.

Be it known that I, Lo'aon O. BURNI-IAM, a citizen of the United States,residing at Clare, in the county of Clare and State of Michigan, haveinvented certain new and useful Improvements in Tile-Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to new and useful improvements in tile makingmachines and isdesigned more particularly as an improvement over thatform of machine granted to me May 241, 1.904, and numbered 760,678, andmy object is to produce a machine of this class whereby drain tile,sewer pipe and the like may be formed of plastic material and the tileafter being formed handled while in a green state.

A further object is to provide means for adjusting the several parts ofmy device whereby the product of the machine will be perfectly true.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings which are made a part of this application,If igure 1 is a perspective view of my improved machine. Fig. 2 is a topplan view thereof. I ig. 3 is a central vertical sectional view. Fig. *1is a horizontal sectional view as seen from line 4-4 3, and, Fig. 5 is adetail sectional view through the machine as seen from line 5 5 Fig. 3.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates the baseof my improved machine, said base comprising crossed arms, to each ofwhich is secured a standard 2, said standards being secured to the armsof said base by means of bolts 3, or the like, and being perfectlyformed of one continuous piece oi metal, the horizontal portions 4.thereof forming a seat for the auxiliary base 5, said base beingpreferably constructed in a single piece and secured to the standards 2in any preferred way as by bolts 6.

A cylindrical core 7 is centrally disposed upon the auxiliary base 5 andis secured thereto by a cap screw 8. Surrounding the base ofthe core 7and at a distance therefrom is a ring 9, said ring being secured tovertil cally disposed bars 10, the upper end of said loars being securedto a ring 11 which sur- I rounds the upper end of the core 7 and at lthe same distance therefrom as the rings 9. The lower ends of the bars10 are reduced to l form bolts which are threaded and disposed throughslots 10 in the auxiliary base 5, nuts 10 being disposed upon thethreaded ends of the bars 10 above and below the base 5 so that one orall of the rods may be raised orlowered to properly adjust the ringsaround the core 7.

A collar 12 is disposed around the core 7 l and is adapted to movelongitudinally there on, said collar being disposed in the space betweenthe core 7 and bars 10 and is longitudinally moved on the core by meansof arms 13, said arms being secured at one end to the collar 12 and attheir opposite end to a crosshead 14, the ends of said cross-head beingdisposed between the respective arms of two of the standards 2, saidstandards serving as guides for said cross-head. The cross-head 14 israised and lowered through the medium of an operating lever 15, saidlever being pivotally secured to one of the arms of the base 1 by meansof links 16, the inner end of the operating lever being iivotallysecured to the cross-head 14 in any yrcferred manner as by eyebolts 17.A cylindrical shell or casing 18 is disposed between the bars 10 and thecore 7, said shell being preferably formed of sheet metal or the likeand of greater diameter than the core 7 so that a space 19 is leftbetween the core and easing into which is adapted to take the plasticmaterial from which the tile or like is made. The shell 18 rests uponthe collar 12, and when the collar is elevated on the core 7 through themedium of the lever 15, the shell 18 and plastic mate rial therein iselevated above the core 7 after which the casing and tile containedtherein is removed and set away to dry.

In order to more readily convey the plastic material into the space 19between the shell 18 and core 7 I provide a cylindrical hopper 20, saidhopper being pivoted at one side to a shelf 21, said shelf extendinglaterally from the ring 11, the outer end thereof being supported bymeans of a brace 22 extending from the shelf and secured at its lowerend to the ring 9.

hen the plastic material is deposited in the hopper 20 should there bemore than i enough to fill the space 19, the hopper is swung to one sideon its pivot point 23 and rests over the uniform edge to the upper endof the tile and of a at the same time removing the hopper an'd contentsthereof from over the tile and casing, so they may be readily removedfrom between the bars 10 when desired.

operation the shell 18 is disposed between the bars 10, the lower endthereof resting upon the collar -12 after which the hopper 1s swung overthe casing and the plastic material deposited in said hopper and afterthe space between the core has been filled the hopper is swung to oneside and over the shelf 21 when the outer end of the lever 15 isdirected downwardly and the casing 18 and the tile therein elevatedabove the ring 11 'when the casing and tile are removed therefrom andstored away to dry. Another casing is then placed in position and theoperation above described repeated.

It will now be seen that I have provided a very cheap, durable andefficient device and one wherein the tile may be handled while of thesame.

What I claim is:

l. A machine of the class described comprising a base, standards 011said base, an auxiliary base secured to said standards, a core on saidauxiliary base, bars disposed around said core from, means to securesaid bars in position around said core, a shelf at the upper end of saidbars, a hopper pivotally secured to said. shelf, a casing between saidbars and surrounding said core and means to elevate said casing wherebythe plastic material may be removed from the core.

2. A machine of the class described comprising a base, standards securedto said base, an auxiliary base on said standards, a core on saidauxiliary base, a plurality of bars surrounding said core and at adistance thereom, a ring at each end of said bars, a casing and at adistance therei I 1' I r I shelf 21 thereby forming an 1 removablydisposed between said bars and than the core whereby plastic material, ashelf at the upper end of said bars, a hopper pivotally secured to saidshelf and adapted to rest thereon when the plastic material is beingremoved and means to elevate said casing and the plastic materialtherein.

3. A machine of the class described comprising the combination with asuitable molding device, of a shelf secured thereto and a hopperpivotally secured to said shelf and adapted to be disposed thereoverwhen desired.

4. A machine of the class described comprising a base, standards on saidbase, an auX- iliary base, a core secured to said auxiliary base, acollar surrounding said core and longitudinally movable thereon, acasing surrounding said core of greater diameter than said core, meansto said casing around the core, arms integral with said collar, across-head at the lower end, of said arms an operating lever pivotallysecured to the central portion of said cross-head, links disposedbetween said operating lever and the base and pivotally secured thereto,and means to adjust said casing with respect to said core.

5. A machine of the class described com prising a base, standards onsaid base, an auxiliary base having slots therein, a core secured tosaid base, bars around said core, rings on said bars, the lower ends ofsaid bars being threaded and disposed through the slots in the auxiliarybase and nuts on said bars to raise and lower the same whereby the ringsmay be alined with the core.

In testimony whereof I have name to this specification in the twosubscribing witnesses.
